I've had a couple gd 'broker' offers over the years...both came in at 600. I countered but never got a reply on either of them. One name (after the 30 day period expired) ended up selling for low x,xxx on another marketplace and the buyer told me that they never received a counter offer from me through the 'broker'. That was awesome for me as my counter was half of what it eventually sold for.
Broker handles everything.

You enter the domain you want in the search box on this page and add Domain Broker Service to your cart. We’ll send you an email
asking for your budget range.
Once we know what you’re willing to pay for the domain, your domain broker will reach out to the current owner to see if he or she is interested in selling.
If the current owner’s willing to sell,
your broker will negotiate on your behalf, with the goal of getting you the name for the lowest possible price.

The Domain Broker Service purchase gives our agents a maximum of 30 days to negotiate a deal for you. Your purchase is non-refundable and non-transferable. If you want to pursue a different domain name instead of the one you originally purchased, you must purchase a separate request to acquire the new domain name through Domain Broker Service.
If we cannot contact the registrant or the registrant refuses to sell, there is nothing more we can do to help you acquire the domain name.
When your Domain Broker Service expires, we make no further attempt to acquire the domain name for you.
We consider the services complete when:
- The Domain Buy Agent made a reasonable, best-effort attempt to contact the current domain name registrant, without response, within the appointed period of time.
- You no longer want to pursue the domain name.
- The current domain name registrant refuses your highest offer.
So if you have been contacted, and the buyer still wants to get the domain name, the broker should normally present buyer's best offer to you.
It is possible that in your case buyer didn't want the domain anymore, or broker didn't do his job properly.
Domain Buy Service and Domain Broker Service is the same thing.
edit:
If the domain owner is willing to sell their domain name to you, your domain name broker will start negotiating prices, starting with the minimum price you chose and working up to your maximum offer. After a price is settled on, an offer is made. Offers are valid for as many as 10 business days and cannot be canceled unless you want to accept a counter offer that was presented by the seller.
